Specification of Letters Patent.

Patented Feb. 18, 1908.

Application filed May 14. 1907. fierial No. 373.665-

To all whom it may concern:

Be it known that I, HENRY F. BEOHMAN, of Battle Creek, in the county ofCalhoun and State of Michigan, have invented certain new and usefulImprovements in Folding Mechanism for Printing-Presses; and I herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, which formpart-of this specification.

This invention is an improvement infolding mechanisms for printingpresses and is particularly designed to be used in connection .withrotary web-printing newspaper presses. Its object is to enable thefolder to deliver newspapers folded either to half-size or toquarter-size, at the will of the operator, and for this purpose theinvention consists more particularly in the novel construction andarrangement of the cutting cylinder, folding cylinder and second-foldrolls, whereby the papers can be delivered by the second-fold rollseither to a receiver for papers folded to half-size or to a third set offolding devices by which the papers may be folded to quarter-size.

In the present invention the cutting cylinder and the second-fold rollsare mounted on adjustable supports which are pivoted axially of thefolding cylinder, so that the cutting cylinder and second-fold rolls canbe adjusted to different positions-peripherally of the folding cylinderso that the papers can be delivered either folded to halfsize or toquarter-size, as desired. By this arrangement the second-fold rolls arealways at the same distance from the cutting cylinder, and the severedsheets travel the same distance from the cutting cylinder to thesecond-fold rolls in either position thereof.

The invention will be fully understood from the following description inconnection with the drawings in which certain well known parts aresimply diagrammatically shown; but the illustration and description willenable anyone skilled in the art to readily construct a folder embodyingthe invention.

In such drawingsFigure 1 is a detail end elevation of such a folder theframe being partly broken away showing the second-fold rolls in positionassumed when the folder is delivering pa ers folded to half-size. Fig. 2is a vertica section through Fig. 1, showing the parts adjusted toproduce papers I folded to quarter-size. Fig. 3 is a plan View. Fig. 4is a side elevation of Fig. 1.

F is a former over which the web is led from the printing mechanismbetween the first fold rolls 1 and 1 located at the a ex of the formerby which the web is folded ongitudinally upon itself before being passedto the cutting cylinder. Over rolls 1, 1% the web is led between cuttingcylinder 2 and folding cylinder 2, the latter being provided with rotarytuckers 2 and collecting pins 2, as usual in such devices. In thisinstance the cutting cylinder 2 instead of being journaled upon thefixed frame has its bearings in hangers 4 which are pivoted axially ofthe folding cylinder 2 and can be adjusted so as to'move the cuttingcylinder 2 around the periphery of the folding cylinder from theposition shown in Fig. 1 to the position shown in Fig. 2. The hangers 4may be connected by tie-rods 4%, and are provided on their upper sideswith segments 4 which mesh with gears 4 on a cross-shaft 4 which can beoperated by a wrench or crank (not shown) applied to itsouter end so asto adjust the cylinder 2 to either position desired. And when soadjusted the hangers can be fastened securely in position by bolts 4which are tapped through the -side frames into the hangers as shown inFigs' 3 and 4, said bolts being removed when the hangers are to beadjusted.

On the hangers 4 and at 90 degrees (or any other desired angle) removedfrom the cylinder 2 are journaled the second-fold rolls 3 and 3 whichare adapted to fold the severed papers to half-size. The rolls 3" and 3may be intergeared as shown at 3 and may be driven by a gear 3 on one ofthe rolls meshing with a gear 2 on cylinder 2, so that the second-foldrolls will be driven in proper speed relatively to the cutting andfolding cylinders.

The cylinders 2 and 2" may have intermeshing gears as shown at 2 2 andcylinder 2 may be driven by gears 2 2, 2 as indicated in Figs. 1 and 4.

The pins 2 are mounted on rock-shafts 2, as usual, said shafts beingcontrolled by a pin-cam 2 at one end of cylinder 2, said cam beingfastened to the adjacent hanger 4 by bolts 2 or in other suitablemanner, so that the pin-cam has a fixed relation to said hangers.Otherwise the construction of the pins and pin-cams and their mode ofoperaisms and needs no detailed explanation.

Below the folding cylinder 2 is a stacker which may be constructed asusual with receiving fingers 6, a rotary fly 6, and endless deliverybelts 6 and when the parts are adjusted in the position shown in Fig. 1,

papers folded to one-half size will be discharged from the second-foldrolls 3 and 3 onto the carrier 6 At one side of the folding cylinder 2is a third folding device which preferably comprises folding rolls 8, 8which may be arranged at right angles to the cylinder 2, and betweenwhich papers may be tucked by a blade 8 indicated in the drawing andoperated in the usual manner. Below the folding rolls 8, 8 is a stackingdevice which may comprise a rotary fly 9 and endless carrier9 which runsat right angles to the carrier 6*. When the cutting cylinder 2" and therolls 3, 3 are swung to the position shown in Fig. 2, the papers will bedischarged from the rolls 3, 3 to this third folding device, and therebythey are folded to quarter-size and delivered onto the carrier 9 Inoperating this folder, if it is desired to have it deliver papers foldedto half-size only, the hangers are swung to bring the cutting cylinder 2and folding rolls 3, 3 to the position indicated in Fig. 1, in whichposition the sheets of paper after being severed between the cylinders 2and 2 are caught by pins 2 as usual and carried around on the cylinder 2until their centers come opposite the rolls 3, 3 then the paper istucked between the rolls 3, 3 by the action of one of the tucking blades2 and the papers are discharged onto the carrier 6 folded to halfsizeand are delivered as usual. If now it is desired to fold the papers toquarter-size, the hangers 4 are adjusted to the position indicated inFig. 2, so as to move the cutting cylinder 2 to a position below thefolding cylinder 2 and move the rolls 3, 3 to a position intermediatethe folding cylinder 2 and the third-fold rolls 8, 8 In this positionthere will be a somewhat longer lead of the web from the rolls 1, 1 tothe cutting cylinder 2, but there will be no longer travel of the cutsheet from cylinder 2 to the second-fold rolls 3, 3? and the papers willbe discharged from rolls 3, 3 to the third-fold rolls or devices 8, 8 bywhich the papers will be folded to quarter-size and discharged fromrolls 8, 8 onto the carrier 9 When shifting the parts from the positionshown in Fig. 1 to that shown in Fi 2, or vice versa, the gear 2 may heslipped out of mesh, so as to allow the folding cylinder 2 to turn onits axis to the extent of the swinging movement of the cylinder 2 andsecond-fold rolls, so that the collecting fingers and tucking bladeswill not get out of time with their respective cams which turn with thehangers; after the hangers are adjusted and fastened the slip-gear canbe replaced.

By the aforesaid construction and arrangement of parts, only one set ofmechanisms is required to operate the folding tucking and collectingdevices, and the operator merely has to remove bolts 4" and slip-gear 2when making the shift from half-size to quartersize deliveries.
